Re: laptops

Sounds like the hard drive is defective. Replace it and run the xp cd.

I bought a dell latitude but it was password protected and i dont have it any suggestion

I'd put Linux on it.


That computer is about 5 years old. Linux works very well with old computers.
Takes up less space, uses less processor power to run, and comes with free versions of pretty much everything.

I don't even think a current version of windows will install on a 5 year old Dell. So you'd be stuck with out of date anti-virus and no updates.

Boot off the Ubuntu disk and just wipe windows.

How to reboot advent intel celeron 15.4'' screen K100: Intel Celeron M 520 Processor 1.6 GHz processor without a CD

What do you mean by reboot? :) do you mean just restart the system, restore it from a previous point or wipe your HDD and go from scratch?

HP 520

See if you can F-11 into your restoration partition.
If not you have already deleted the main and secondary partition, all is lost.
Remove the drive and hook it up to another PC and see if you can review it.
If not start from scratch

I want to upgrade my hpdv1000 pentium M processor whats the maximum upgrade allowed for this? i have upgraded it to 2gb ram from 512mb and 250gb hd from 60gb and its doin fine.

You should be able to upgrade the CPU, since it seems that the DV1000's motherboard uses a socket CPU design. But, obviously, HP would rather have you choose the CPU that you want from the beginning and stick with it.
The first thing to do is to check HP website to see what other configurations were/are sold for your model. If they sell it with faster CPUs then you can upgrade to one of them...

In order for a particular processor to be compatible with a particular laptop:
(1) the processor must be physically compatible with the laptop socket, in your case I thing you have a Soket 479 processor
(2) the laptop chipset must support the processor.
(3) the chipset front side bus speed must match the processor front side bus speed, in your case 400Mhz.
(4) the laptop BIOS must support the processor.

So I listed here processors with FSB at 400Mhz, I gues that DV1000 as a 855GM Motherboard that supports only 400Mhz with Socket 479

Pentium M

Pentium M 1.3 1300 1024 400
Pentium M 1.4 1400 1024 400
Pentium M 1.5 1500 1024 400
Pentium M 1.6 1600 1024 400
Pentium M 1.7 1700 1024 400

Pentium M 710 1400 2048 400
Pentium M 715 1500 2048 400
Pentium M 725 1600 2048 400
Pentium M 735 1700 2048 400
Pentium M 745 1800 2048 400
Pentium M 755 2000 2048 400
Pentium M 765 2100 2048 400

Celeron M

Celeron M 310 1200 512 400
Celeron M 320 1300 512 400
Celeron M 330 1400 512 400
Celeron M 340 1500 512 400

Celeron 205 1200 512 400

Celeron M 350 1300 1024 400
Celeron M 360 1400 1024 400
Celeron M 370 1500 1024 400
Celeron M 380 1600 1024 400
Celeron M 390 1700 1024 400

Same wireless problem

Check with your laptop's manual. The wireless switch is usually hidden in a spot that makes it difficult to find, basically so that you cannot hit it by accident.
For example, a Compaq Presario R3000 has a button on the exact left hand corner of the front of the notebook, such that it cannot be seen easily, but when you push it to activate wireless, you will see a very faint light blue icon near the right front button.
On an HP laptop,the wireless button is on the bottom.

On my ACER, there is not button. It is an automatic switch between wire and wireless.

So look carefully for the switch, because if there is such a switch, it will be difficult to find. But it is most likely that there is no switch at all.

Upgrading my laptop's processor from celeron 540 to 560

there is no way you can upgrade the VGA on a laptop. You can upgrade everything else. But tis always better and cheaper to get a new one.

check with the cost of the celeron 560 and the 4gb + the 250 gb together.

but how much a new computer cost? so its your choice...
